7 Science Tricks with Surface Tension

The video explores various experiments demonstrating surface tension and other phenomena. It starts with creating colorful patterns using milk, food coloring, and soap. The presenter then shares a discovery of soapy spheres in coffee, which can be recreated with other liquids. A soap-powered boat is demonstrated, followed by a trick where surface tension holds water in a jar with a screen. The video also shows how a paperclip can float on water and the effect of soap on it. Finally, the Leidenfrost effect is illustrated with water droplets on a hot pan.
